The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.
The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.
So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

Answer:
The top Predators
Explanation: The top predators are the least numerous organisms to maintain the population of the other organisms. If the top predators were the most numerous than the species in the forest would go extinct because they would eat all of the organisms lower on the food chain and would therefore starve to death. The top predators maintain the population of the forest by eating the lower organisms so that the amount of plant life will not go extinct.
